Abstract

Des exemples de modes de réalisation de la présente divulgation concernent la configuration de mesure pour l'agrégation de porteuses et une double connectivité. Un équipement terminal obtient, à partir d'un dispositif de réseau, au moins une configuration de mesure. La ou les configurations de mesure indiquent au moins l'un parmi : au moins un événement de rapport de mesure, ou au moins une bande de fréquence à mesurer. L'équipement terminal stocke la ou les configurations de mesure. L'équipement terminal transmet, au dispositif de réseau, au moins un rapport de mesure sur la base de la ou des configurations de mesure. Le ou les rapports de mesure comprennent des informations associées à la ou aux bandes de fréquence. De cette manière, le rapport de mesure peut être rapporté sur la base de la configuration de mesure. Un tel rapport de mesure peut être utilisé pour l'établissement précoce d'une agrégation de porteuses et/ou d'une double connectivité.
